Title: Transmission signal level control device for radio transmitter
Inventor: SHIBATA TAKAYUKI
IPC: H03G3/30
Filed: 1993-02-16
Abstract: ABSTRACT OF THE DISCLOSURE       In  order  to  realize  control  of  a  transmission siganl  level  from  a  radio  trasmitter  of  TDMA  (Time Division Multiplex  System)  with a  simplified  arrangement and with a high precision,  a control circuit 9 outputs a transmission  signalfor  each  time  slot  and  a  level designation   signal.   A   levelcontrol   signal   generator circuit 4 generates a level control signal in response to the  level  designation  signal  and  outputs  the  level control signal through D/A converter 5 to a level control circuit  2.   The  level  of  the  modulated  transmission signal  is controlled by the level  control  circuit 2 and is  amplified by a RF amplifier circuit  3  thereby being output  outside.  The  output  level  is  detected  by  a detecter  circuit  8  and  fedback  through A/D  converter  7 and a detection characteristic storage circuit 8 to level control  signal generator circuit 4 so that  the value of the level control signal is corrected.

Title: Positive pressure canister purge system integrity confirmation
Inventor: BUSATO MURRAY F
IPC: F02M25/08
Filed: 1994-01-27
Abstract: The tank/canister volume's integrity against unacceptable leakage measured by a diagnostic test performed by an on-board diagnostic system which includes an electrically operated air pump (24) and tank-mounted analog pressure transducer (28). At the beginning of a test, the engine management computer (22) closes the canister purge solenoid valve (12) and operates the pump to begin pressurization of the tank/canister volume. The pumped air is introduced via the canister's atmospheric vent port (14V) at a regulated pressure. Failure to build tank pressure to a predetermined pressure within a predetermined time indicates a gross leak. If no gross leak exists, the pressure will build, and the time required to build to a given pressure from the start pressure provides a measurement of any leakage that may be present. The fuel fill level in the tank affects this time, and it is taken into account in the measurement.
